Creating screenshots
You can create screenshots either using the Print Screen button on your keyboard and then pasting the image into any image editor, such as M$ Paint, and saving it as a PNG image, or better just install a proper image editor, like the free open source Gimp (links for Windows and Mac at the bottom of the page). To create the screenshot in Gimp, click on File > Create > Screenshot.
Comparison of raster graphics editors
Regardless of what program you use, its best if you save your screenshots to the PNG format (use maximum compression), and never resize them (unless you really need to and know what you are doing), since we sometimes have problems when people make their screenshots so small one cannot make anything out. If you want to use JPG, they will look nicer if you disable subsampling (1:1:1).

Once you create a screencast, use one of the file hosting sites listed above to upload it and then paste the link to it to the appropriate thread in the forum.

- I think the best place for this concise info is in the announcements section, but I cannot create posts there. If any mod moves this thread there, please also remove this post.
- There is a large free area of wasted space after the closing [/code ], perhaps you could tweak the CSS to prevent it.
- This version of punBB won't let me include a [code ] tag inside an existing one, so I had to add a space so that it doesn't get treated as a tag inside my code example. Perhaps an update to punBB will fix that. phpBB-2.0.23 lets me do that.
- I don't see the point of including the countless proprietary screencast/image editor/etc programs, perhaps a link to the appropriate wikipedia "list of * / comparison of *" page should be included. Only including the good open source ones seems worthwhile to me, since everyone can get them and since there are many open source projects still/eternally in an unusable state, or dead. I included the ones I personally tested, except for camstudio, i used an older version, not this newer one I linked.

I have used the Windows version of Camstudio. It works very well and increases your productivity. I automatically zooms in to the area you are clicking and has an excellent codec.

Thanks a lot DrSlony for this nice introduction. Why not beeing transformed into a mod so that you can post directly in the announcement ?

If this Print Screen key works on Mac, Unix and Windows it would be useful Autopano being able to get the screen image (Hmmm...) and save it in a proper format at a convenient place (its own temp dir? the current images dir?) with date, time, OS, version, etc included in one of the image corners.
BTW, hitting a key to save, retrieve and upload screen captures would be a useful feature when used to post in forums like this one or to send emails ...

Heh, we cannot get around to updating punBB 1.2 to 1.3 (a minor version) and fix the forum admin css, or install a simple plugin, let alone alter the bbcode representation!
Thanks Maciek for the exhaustive post. Now all you have to do is make people read it. I can stick it in bright red in the Announcement bar above, but I don't really think it will help. Still, I'll do it.

GURL: I like the screenshot auto-taking and auto-saving to disk idea! But I'm not clear on what you mean by "retrieve and upload", retrieve from where? Upload to where? Some imagebin? This forum in a new post?
[bo]: "stick it in bright red in the Announcement bar above" would be good, and then we can just point people to this instead of repeating the same things over and over.

Saving is not enough, if I save more than one screenshot or save several window contents in a row I must retrieve the right ones, edit them and use them...

For screen recordings there is http://screenr.com/ - its super easy to use, and its free. It gives you an embed code and url. At work I use both Captivate from Adobe and Articulate Studio to develop elearning. If you have Captivate it is possible to record fullmotion video with it, but I would just go for Screenr for short videos, up to 5 min - much faster.
Another free alternative is Jing (http://jingproject.com/), you can host video files locally or on your own server. Jing is made by TechSmith, who also develops Camtasia.
A shortcut to screenshots on a mac is to use shift+cmd+4 which gives you .png files autosaved to your desktop.

To just upload a screenshot image, I use uploadscreenshot.com. You can just printscreen to screenshot your entire screen, or alt-printscreen to screenshot a window, and it will be copied to your clipboard. If you go to uploadscreenshot.com, you can paste the screenshot image in your clipboard to the site, and it will be uploaded. After upload, it gives you a link to a BB Code that will display a thumbnail of the image in your post which will link to the full size image.

uploadscreenshot.com seems the best solution *IF* you have Java Runtime installed.

I spoke with the guy who runs imagebin.ca and convinced him to allow hotlinking, so if you had problems with that site in the past, they should be gone now.
Offline
and public available files (APT resources AND AP resources) also can be uploaded via kolor/autopano wiki:

Is a simple, easy, time saver program for $29.95. You can easily crop, edit and add notations, etc. Well worth the $$.

Easily take and upload screenshots in Linux
Below is a great script for taking a screenshot of the whole desktop, a window you click on or a rectangular region you select with your mouse, and automatically uploading it and copying the url into your clipboard ready for pasting!
Save this script to a file in /usr/bin, let's call it /usr/bin/shoot
Now create a new shortcut to it in your window manager, for example in KDE4 I fire up "Custom Shortcuts" (ALT+F2 > hotkeys) and create a new "Global Shortcut > Command/URL", in the Trigger tab bind it to Shift+Print and in the Action tab set Command/URL to /usr/bin/shoot
Now just press Print Screen while holding Shift, and either click a window or select a region. The screenshot gets taken and uploaded and you will get a popup notify telling you the url is ready in your clipboard :]
#!/bin/bash
#
# Original "shoot" script header below, however the script was largely edited by DrSlony.
#
# By Sirupsen @ http://sirupsen.dk
#
# Description: Very simple script to make you
# select a region of your screen, which will be captured, and
# then uploaded. The URL will then be injected into your clipboard.
#
# Dependencies:
#
# Imgur Bash Upload Script (http://imgur.com/tools/imgurbash.sh)
# Comment: Must be in path (see below) with the name "imgur" (not imgur.sh)
#
# Scrot
# Comment: Scrot is what takes the actual screenshot.
#
# Xclip
# Comment: Xclip is what makes the script able to inject the direct url
# into your clipboard.
#
# libnotify*
# Comment: Will notify you whenever the direct URL is in the clipboard
#
# Installation:
#
# Move the file to a local bin. And put the path of this bin, into
# your path. (See: www.troubleshooters.com/linux/prepostpath.htm)
#
# From then on, you can either activate it via your terminal, or via
# your window manager or similar, so you can bind it to a keycombination.

better upload it publicly.
i strongly suggest photobucket or flickr or even mediafire, that way you can have a backup of your files.
